The cap is 75% — but the number you need from gear is higher
Fire, Cold, Lightning and Chaos resistance each cap at 75% by default. A handful of passive nodes and uniques explicitly raise that maximum to 90% instead.
The trap is assuming “75% of resistance on my gear” equals “75% on my character”. It does not. The campaign applies a resistance penalty at progression milestones, so the same ring that capped you in an early act leaves you short later. Published figures for the penalty have shifted as the act structure was reworked during Early Access, and community sources currently disagree on the exact per-stage numbers.
So do not trust a fixed penalty number from a guide. Read the live number: open the Character screen (C) and the Defence tab. That value already has your gear, passive tree, and the current penalty baked in. It is the only number that stays correct across patches.
Fix the biggest single gap first
Priority order matters more than it looks. One element sitting 30% below cap is far more dangerous than three elements each 10% below, because the badly short element is where a single big hit kills you. Work down from the largest gap rather than topping up whichever slot you happen to be re-rolling.
Where the resistance comes from
| Source | What it gives | Note |
|---|---|---|
| Rings, amulet, belt | The bulk of your resistances | Look for dual-resistance suffixes — one affix slot covering two elements |
| Armour pieces | Resistances plus defences | Secondary source; also the slot for resist runes |
| Runes | Cheap socketed resistances | Socket into armour, not weapons — in a weapon the same rune adds damage, not resistance |
| Passive tree | Some resistance nodes | Supplement only; gear and runes are more efficient |
| Chaos resistance | Its own bucket | Not reduced by the campaign penalty; matters because chaos damage bypasses energy shield |
Rules that keep you capped
- Read the Defence tab, not a guide’s penalty table. The campaign penalty has been reworked more than once.
- Re-check after every gear swap. Dropping a resistance-heavy ring for a damage upgrade is the most common way to silently fall out of cap.
- Cap before act bosses and before your first map. Map enemies deal far more elemental damage than campaign enemies.
- Never enter hard content uncapped. At 75% you take a quarter of the incoming elemental damage; at 50% you take double what a capped character takes.
- Sort the three elemental resistances first, then chaos.
